Bug description:
I updated to latest kernel: initrd.img-5.3.0-43-generic and find that
bluetooth is enabled and no wireless connection. When I stop bluetooth I go
into airplane mode. I cannot find any wireless connection in network or
wireless connection setup in settings. ifconfig shows there is no wireless
interface setup. When I go back to kernel 5.3.0-42 everything is working
correctly. I am using an HP laptop.
I can see the wireless network controller with lshw:
lshw -C network
